My first Thermoquad tuning question!

hi, how many wraps on air door spring? also, the choke linkage has to be blocked open.
on throttle side of carb. you don't want it to move at all. I think your air door is too tight. on our 340, its set vertical, then tighten spring until it just closes. mine would blubber in water box, before. a s/s racer said door was too tight. it was opening and closing. so , loosened it up, problem went away. also, did you drill out back of vacuum canister? we done that, it let 's door open faster, without delay. BTW , this is a 340 stocker. not a street car!!!
